Android Question Error when 10.7

[denik]

Dear Sirs!
When I install B4A ver 10.7, I receive such error

java.lang.NoSuchFieldError: No static field ac_spinner_row_layout of type I in class Lanywheresoftware/b4a/objects/R$layout; or its superclasses (declaration of 'anywheresoftware.b4a.objects.R$layout' appears in base.apk)

Earlier (before version 10.7) there was no such error
Are there any solutions?
Thanks in advance

Problems with 10.7 are almost always due to an incorrect installation process.

You need to follow ALL the install instructions exactly from here: https://www.b4x.com/b4a.html

Also you need to get bundletool.jar and install it as described here: https://www.b4x.com/android/forum/threads/b4a-v10-7-is-available-for-download.128734/#content

I guess this is not the reason. Most projects recompiled fine. And in this

java.lang.NoSuchFieldError: No static field ac_spinner_row_layout of type I in class Lanywheresoftware/b4a/objects/R$layout; or its superclasses (declaration of 'anywheresoftware.b4a.objects.R$layout' appears in base.apk)
at de.amberhome.objects.appcompat.ACSpinnerWrapper$ACB4ASpinnerAdapter.getView(ACSpinnerWrapper.java:465)
at android.widget.AbsSpinner.onMeasure(AbsSpinner.java:206)
at android.widget.Spinner.onMeasure(Spinner.java:614)
at androidx.appcompat.widget.AppCompatSpinner.onMeasure(AppCompatSpinner.java:436)

seems to be some kind of problem with ACSpinner.
But maybe this is somehow solved without rewriting the code?

Why not use a regular Spinner? Android 4 devices are mostly not relevant anymore. AppCompat is not really needed.

Try this project: https://www.b4x.com/android/forum/threads/appcompat-with-toolbar-minimal-example.79896/#content
If it is not working then there is a configuration problem.

Had the same problem with 10.7 until I discovered that in some cases I defined global 'X as X' instead of 'X1 as X'. I was that simple.
